Authorities allege it was Ciancia who opened fire inside the airport the morning of Nov. 1, killing Transportation Security Administration Officer Gerardo I. Hernandez and wounding three others. Ciancia was shot in the head and leg during a gun battle with police.

Ciancia was initially listed in critical condition. He was upgraded to fair condition on Nov. 12.

Ciancia has been charged with the murder of a federal officer and the commission of violence at an airport. If convicted of the charges, he could face the death penalty or life in prison without parole.

Authorities allege that Ciancia targeted TSA workers in the attack and had written in a signed note that he wanted to kill TSA agents and "instill fear in their traitorous minds." Witnesses to the shooting said the gunman asked whether they worked for the TSA before moving on.
